Compare any two graphics cards:
GeForce GTX 550 Ti vs Radeon HD 4870 1GB
IntroThe GeForce GTX 550 Ti features a GPU clock speed of 900 MHz, and the 1024 MB of GDDR5 memory runs at 1026 MHz through a 192-bit bus. It also is made up of 192 SPUs, 32 TAUs, and 24 ROPs.Compare all of that to the Radeon HD 4870 1GB, which features clock speeds of 750 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 800(160x5) SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 4870 1GB is 17% faster than the GeForce GTX 550 Ti overall, due to its greater bandwidth. (explain)
Texel RateThe Radeon HD 4870 1GB should be a little bit (about 4%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 550 Ti should be quite a bit (about 80%) faster with regards to anti-aliasing than the Radeon HD 4870 1GB, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.

Wow!
I bought the 550 Ti last week... but I didn't realize it would give me such good performance... even for a hardcore gamer like me \m/
🙂
Hello! 😉
I bought recently the ASUS GTX550 Ti DirectCU because my 8800GT 'crashed and burned' and I'm really very pleased with it!
It has an amazing cooling system and allready brings a factory OC, it also has a volt tweak (VCore) to increase performance up to a stunishing 50%!
All these functions are controlled by an ASUS application, you can do it manually or let it auto-configure (like the 'HyperDrive' feature)....and the temperatures are always between 35º/45º, incredible!
In theory, with the OC and VCore enabled, this card can be superior to the 'normal' GTX560....wow!!
